i have a problem with breaking my rear bulkheads on my emaxx brushless, i like to jump my truck just not sure if its a good idea to buy aluminum or not. i bash my emaxx pretty hard but i dont want to change those to aluminum and then make a chain reaction and start changing everything to aluminum ya know. just wondering what you guys think i should to or if anyone has everything plastic except the bulkheads and have had any problems running it like that. thanks.
